The 25-year-old Illinois man shot in an Ann Arbor bar early Sunday is in stable condition and expected to survive, police said.

Detective Lt. Robert Pfannes said police were dispatched at 12:44 a.m. Sunday to Rush Street, 314 S. Main St., for a report of a shooting. A 25-year-old Westland man shot at the Illinois man twice before being tackled by patrons, Pfannes said.

“Initially, two citizens jumped on him,” Pfannes said.

Police arrested the Westland man after a struggle. He was still in custody Sunday morning and he’s expected to be arraigned Monday on criminal charges, Pfannes said.

The men argued before the shooting, Pfannes said. He said investigators believe the men were strangers to each other.

It was a chaotic scene at the dance club on the main strip of Ann Arbor’s Main Street bars early Sunday morning. Jonathan Barkan was attending a birthday party at the bar and was about 20 feet away from the shooting.

Barkan told The Ann Arbor News the two gunshots he heard were the first indication anything was wrong. There was about 20 seconds of calm before panic gripped the club.

“People were screaming and pushing each other,” Barkan said. “It was like that scene out of a movie where everyone was just scrambling away.”

Barkan said his first move was to call 911. He walked over to the area where the Illinois man was shot and described what he saw to dispatch.

The man was conscious but appeared to be in shock, Barkan said. He was shot once in the abdomen and wasn’t screaming or moving.

“The only thing I thought was to go get information to 911 to make sure, when police were there, they could help this guy,” Barkan said.

Tommy Helderop was also inside the bar at the time of the shooting. Much like other witnesses, Helderop said he didn’t hear the argument that led to the shooting, and wasn’t aware anything was wrong until he heard gunshots.

The gunshots were louder than the club’s music, Helderop said.

Pablo Trefftz, who was with Helderop at the bar, said they cleared out as fast as they could after police arrived.

“I don’t want to be here at all right now,” he said.

Police who responded the scene closed off South Main Street between Liberty and William streets for a matter of hours while they investigated the shooting Sunday morning. Investigators were still on scene as of about 3:45 a.m. Sunday, but the street was open by that point.

Barkan said police came into the bar and tried to handcuff the Westland man, but he put up a fight. Eventually, police used a Taser on the man in order to bring him under control and put him in the back of a patrol car, Barkan said.

The woman whose birthday Barkan was celebrating is a trained emergency medical technician and ended up helping first responders bandage the victim at the scene, he said. It was all a very shocking experience, Barkan said.

“I definitely didn’t sleep too much last night,” he said. “It is strange, because you see something like this in movies. … Suddenly, I was an actor in that scene and it was not a sort of pleasant situation.”

Barkan praised the Ann Arbor police officers who responded to the incident and said he was angered when he heard passersby lobbing random insults at the police.

“The Ann Arbor police, the people that showed up, were incredibly efficient,” he said. “They were amazing. I feel very good with them around.”

Police continue to investigate the incident. Anyone with information is encouraged to call the Ann Arbor police anonymous tip line at 734-794-6939 or Crime Stoppers at 1-800-SPEAK UP (773-2587).
